The purpose of this paper to present the findings of a research study developed by the Town of Jupiter and the University of Central Florida (UCF). Research was conducted to address the in-plant blending operations, distribution system corrosion issues, and disinfection separately. A description of the approach to corrosion testing is provided, which included construction of a test apparatus to monitor corrosion activity of mild steel, lead solder and copper metallic components under changing test conditions. Corrosion assessment included the evaluation of various blended orthophosphate corrosion inhibitors. The challenges related to post treatment disinfection are also discussed, and how the subtle changes in finished water pH affected chloramine chemistry and stability. Results of the research effort were used to identify and implement a post treatment system that would effectively address the unique conditions of the Town?s water system. The content herein is intended to highlight the complexities associated with integrating membrane processes into an existing distribution system and to recognize the importance of considering post treatment during the planning, design, piloting as well as operational phases of a membrane related project.
